Response Curve

Radiant Beam Intensity detector assembly includes an LED barrel to block ambient light and easily establish the working distance for measurement of radiant beam intensity in Watts/steradian.

Measurement Range: 3.5e-9 to 6.6 Watts/steradian
Spectral Range: 400 - 1064 nm
Order part number: ILT5000*, SED033/F/LED (detector)
* Software Included / Tablet PC Sold Separately

Applications: This detector is equipped with our Flat response correction filter designed to create a more uniform sensitive response in the VIS-NIR range. Typically used for radiant beam intensity output of discrete LEDs, small LED modules, or small lamps with calibration for direct readings in  Watts/steradian). Note (aperture was increased to 9.27 mm 6/17.  The aperture is used to block ambient light and align the LED.  It can be unscrewed and removed to allow placement over mounted LED's as shown in the sensor assembly photo.)


SED SEL 033 Filter






Filters and input optics are removable and may be ordered separately from the detector assembly to allow filter and input optic swapping.


For simultaneous multi-sensor data logging, ILT also offers the ILT6000 Rack-Mount Radiometer System with the same specifications as the ILT5000 in a 2-10 unit, rack-mountable housing.
